Description:

TECHNICAL FIELD

[0001] The present invention relates to a closure device for a container
storing a first medium, which has a chamber for storing a second medium.
The chamber may be filled, for example, with a medicament forming the
second medium, which with the aid of the closure device according to the
invention can be decanted in a predetermined quantity into the container,
in which there may be, for example, water as the first medium. The
invention also relates to a set of components for manufacturing a closure
device according to the invention.

BACKGROUND

[0002] DE 88 14 315 U1 discloses a mixing device for adding a flowable
additive to a paint in a closed container. The mixing device comprises a
closed capsule in which the flowable additive is stored. The additive is
introduced into the container by reducing the interior volume of the
chamber.

[0003] WO 2009/031167 A1 discloses a closure device having a chamber for
storing a miscible component. The chamber is closed on its lower surface,
primarily by a lid. To open the lid, the closure device must be rotated,
displacing a tubular part of the chamber in a downward direction and
forcing the lid to open.

[0004] A closure device having a chamber for provision of a further medium
is known from U.S. Pat. No. 4,982,875. The chamber is closed on its lower
surface by a lid on which a tubular part of the chamber is positioned.
The chamber is opened by rotating a cap of the closure device, by which
means the tubular part is displaced and the lid forced to open.

[0005] US 2008/0223740 A1 discloses a closure cap that on its interior
surface has a tubular projection which forms a chamber for storing a
further medium. The tubular projection is closed by a sealing member
attached to the container opening. If the closure cap is unscrewed from
the closed container, the sealing member remains in the container, with
the result that it frees the tubular projection and the medium stored
therein is able to flow out into the interior of container.

[0006] DE 85 02 008 U1 discloses a closure cap for two-component packages
having an inner container for accommodating a concentrate. A closure cap
base of the closure cap has a collar extending into a bottle neck, which
collar has a collar thread onto which the inner container may be screwed.
The interior wall of the bottleneck has at least one anti-rotation lock
so that, by rotating the closure cap, the inner container is unscrewed,
whereupon the concentrate can flow out. A drawback of this solution is
that the collar thread and the thread of the inner container make
manufacturing the closure cap very expensive.

[0007] Drink packages are known from WO 92/02434 A1, which make it
possible to mix two components. FIG. 7 of WO 92/02434 A1 depicts a
container which is closed by a closure cap on which is formed a tubular
chamber for storing another component. The tubular chamber projects into
the interior of the container and is closed by a closure stopper. When
the closure cap is pulled off, the closure stopper is removed from the
tubular chamber, whereupon the component contained therein can flow out.
However, it is not shown how the tubular chamber can be filled and closed
when it is in the container. To this extent the solution shown cannot be
implemented. Regardless of this, the disadvantage of this solution is
that the sealing tightness of the closure stopper on the tubular chamber
is limited. If the press-fit of the closure stopper on the tubular
chamber is strengthened to increase the sealing tightness, the chamber
can only be opened with much force by removing the closure cap.

[0008] EP 1 582 331 A1 describes a closure device for a bottle containing
a first medium. The closure device comprises an inner, tubular region to
receive a second medium, which is introducible via a raw-materials inlet
temporarily closed with a top lid. The tubular region is closed by a
lower lid on a side facing the interior of the bottle. The lower lid
closes the tubular region via a predetermined tear line. By guiding of
the tubular region out of the mouth of the bottle, the lid is opened by a
tearing of the predetermined tear line. Following opening of the tubular
region, the lid serving to close this region falls into the bottle,
because the predetermined tear line is circumferentially separated during
opening of the closure device.

SUMMARY

[0009] Taking the prior art as a starting point, the aim of the present
invention consists in providing a closure device for a container storing
a first medium, having a chamber for storing a second medium, in which,
even after opening of the chamber, no constituents of the closure device
are able to find their way into the container storing the first medium.

[0010] The above-mentioned aim is achieved with a closure device according
to the appended claim 1. The aim is furthermore achieved with a set of
components for manufacturing a closure device according to the appended
dependent claim 8.

[0011] The closure device according to the invention serves to close a
container storing a first medium. The container may be, for example, a
glass or plastic bottle in which water is stored as a first medium. The
water may, for example, be a first component of a medicament solution to
be prepared, or even of an alcoholic or alcohol-free drink to be mixed.
The closure device according to the invention comprises a closure cap for
closing a through-opening. The through-opening may be formed directly on
the container, or also in a flange of the closure device. In any case,
the closure device in its entirety closes an opening of the container.
The through-opening may serve, for example, to deliver the first medium
stored in the container or the mixture to be prepared therein.

[0012] The closure device according to the invention further comprises a
chamber for storing a second medium. The second medium may be, for
example, a medicament in powder form which is to be dissolved in the
first medium. The second medium may also be fluid, for example in the
form of a syrup or a spirit. The second medium is stored in the chamber,
so that the user may, at a time of his or her choosing, cause the first
medium and the second medium to be mixed through a use of the closure
device according to the invention.

[0013] The chamber preferably has a wall which is per se unmovable, i.e.
it has no components movable relative to one another such as, for
example, mutually displaceable tubes. The chamber is guidable into the
through-opening, wherein the chamber is positioned in the through-opening
in a closed, ready-for-use state of the closure device. The chamber is
fastened to the closure cap on a side of the closure cap turnable to face
the through-opening, for example in that it is formed integrally with the
closure cap. The chamber is furthermore closed, on its side turnable to
face the interior of the container, by a lid which is preferably formed
integrally with at least one part of the chamber. The lid serves to
enable the chamber to be opened in order to convey the second medium into
the first medium.

[0014] According to the invention, the lid closes the chamber via a closed
predetermined tear line by means of which a sealed closure of the chamber
by the lid is ensured. The lid further comprises an actuating member,
with which the lid is opened by tearing of the predetermined tear line
during guidance of the chamber out of the through-opening. The chamber is
in particular guided out of the through-opening when the closure device
is opened by removing the closure cap. This happens when the closure cap
is unscrewed or pulled off. During guiding of the chamber out of the
through-opening, the chamber is drawn at least partially out of the
closure device, during which it moves in a direction towards the interior
of the container. In this arrangement the actuating member, which is
preferably disposed outside the chamber, forces the lid to open.

[0015] The chamber comprises a filler tube fastened to the closure cap,
and a lid insert. The lid is formed integrally with the lid insert. The
lid insert is fastened in the filler tube via a sealed connection. In
this arrangement, the lid insert is preferably designed in the form of a
stopper for the hollow filler tube. This allows simple filling of the
chamber with the second medium. For this, in the first instance the
closure cap with the filler tube fastened thereto is screwed on to the
flange or on to an opening of the container. At this point, the lid
insert is not yet positioned in the filler tube, with the result that the
filler tube of the chamber can be filled with the second medium. The lid
insert is then fixed in the filler tube, for example by pressing the lid
insert into the filler tube. Fastening of the lid insert in the filler
tube, which comprises for example a welded, pressed or glued connection,
ensures a sealed connection of the lid insert in the filler tube, with
the result that the chamber is completely sealed off. Since the lid
insert is now permanently fastened in the filler tube, the lid will open
at the predetermined tear line during use of the closure device.

[0016] The lid can be pivoted via a hinge towards the lid insert. The lid
insert, lid and hinge are integrally formed.

[0017] A particular advantage of the closure device according to the
invention is that the chamber is suitable for storing media which, until
they are used, must be fluid-impermeably, or preferably air-impermeably
separated from the medium stored in the container. And yet, easy opening
of the lid by tearing off the predetermined tear line is made possible by
the actuating member on the lid, with the result that the container
closed with the closure device according to the invention can be opened
for example with only one hand. The predetermined tear line may be
created in such a way that it can be torn open with very little force.

[0018] The closure device according to the invention can also function as
a dose-metering device in order, for example, to add powdered medicament
as a second medium into water as a first medium, making it possible to
dispense with medicaments in tablet form.

[0019] In a preferred embodiment of the closure device according to the
invention, said device also has a spindle arrangement, through which, in
order to open the lid, the actuating member (19) is displaced towards the
chamber by rotating the closure cap with the chamber fastened thereon.
The spindle arrangement enables the rotatory movement during opening of
the closure cap to be converted into a translational movement which
distances the actuating member on the lid relative to the chamber, as a
result of which the predetermined tear line is torn open. With a slight
torque to open the closure cap, large forces can be generated to open the
lid. However, the invention is not limited to closure caps which have to
be unscrewed to open them. The closure device may also be produced in
such a way that the closure cap is pulled off for opening, by which the
accurate actuating member is similarly distanced from the chamber.

[0020] The closure device according to the invention furthermore
preferably comprises a flange for mounting the closure device on an
opening of the container. With this arrangement, the through-opening is
formed in the flange. The flange preferably has an inner thread, with
which the flange can be screwed onto the opening of the container.
Furthermore, the flange preferably has an outer thread, onto which the
closure cap can be screwed. The through-opening formed in the flange
serves for receiving the chamber and delivering the mixture formed from
the first medium and the second medium. The flange is preferably
rotation-symmetrically formed, so that the cylindrical through-opening is
arranged coaxially to the inner thread and to the outer thread. The
closure device, comprising the flange, closure cap and chamber, can be
provided to the user separately or in combination with the container.

[0021] The spindle arrangement preferably comprises a first thread on the
flange and a second thread on the closure cap. With this arrangement, the
closure cap can be screwed, with the second thread, onto the first thread
of the flange and can be unscrewed therefrom. Here, the first thread and
the second thread have two functions. The first function consists in the
ability to screw the closure cap on to the flange in order to close the
closure device. The second function consists in the fact that, when the
closure cap is unscrewed from the flange, not only is the closure device
opened but also simultaneously the lid of the chamber, in order to be
able to deliver the second medium from the chamber into the first medium
in the container. The flange can also be designed as an integral
component of the container.

[0022] The actuating member is preferably formed by a projection, by which
the lid projects beyond the through-opening in its cross-section. In this
arrangement, the actuating member is preferably formed integrally with
the lid. The projection prevents the lid from sticking in its orientation
crosswise to the through-opening during passage of the chamber via the
through-opening. The lid is forced by the projection to change its
orientation, as a result of which the predetermined tear line is torn
open. In the opened position of the lid, the lid is in an orientation
diagonal or longitudinal relative to the through-opening, with the result
that the lid with the projection can be guided through the
through-opening together with the chamber.

[0023] The spindle arrangement preferably comprises an upwardly sloping
guide edge, which is arranged on a side of the through-opening turnable
to face the interior of the container. By rotating the chamber towards
the through-opening, the projection is guided over the upwardly sloping
guide edge, with the result that the rotary movement of the chamber and
the lid is converted into a translational movement of the projection
towards the chamber. The upwardly sloping guide edge may be formed, for
example, as a connecting link. The spindle arrangement can alternatively
or jointly comprise the two threads on the flange and the closure cap, as
well as the upwardly sloping guide edge. The spindle arrangement may,
however, also comprise other elements alternatively or in addition, by
which, by rotation of the chamber with the lid, the actuating member is
moved at least partially in a translational manner towards the chamber.

[0024] In an alternative further embodiment, the chamber has a sealed
opening on a side turnable to face the closure cap. In this embodiment,
filling of the chamber takes place via the sealed opening. Following
filling of the chamber and sealing of the opening, the chamber is to be
fixed to the closure cap, for example in that a snap connector is formed
between the chamber and the closure cap. In this body meant the lid is
preferably formed integrally with the chamber.

[0025] The chamber is preferably in the form of a cylinder, wherein the
lid is formed on a circular base area of the cylindrical form. The
cylindrical form is especially suitable for being arranged in a
cylindrical through-opening. In this arrangement, the lid is formed on
that circular base area of the cylindrical form that is turnable to face
the interior of the container.

[0026] The lid is preferably in the form of a circular segment which forms
a circular base area of the cylindrical form. A a weakening of the
material is preferably present on the rectilinear transition from the
circular segment-shaped lid to the remaining part of the circular base
area, in order to form the hinge for the lid. The lid can be flipped open
towards the chamber with the aid of the hinge. In this arrangement, the
predetermined tear line is preferably formed on the circular arc-shaped
circumference of the circular segment-shaped lid. The predetermined tear
line is also preferably formed by a weakening of the material, wherein
the material there must be weakened distinctly more than on the hinge.

[0027] The mid-point angle of the circular segment-shaped lid is
preferably between 45° and 340° ; especially preferably
between 130° and 160°.

[0028] In an especially preferred embodiment of the closure device
according to the invention, the lid is in the form of a right-angled
section of the circular base area of the cylindrical form. A weakness in
the material is present on one of the four sides of the rectangular
shape, at the transition to the remainder of the circular base, to form
the hinge. The rectangular lid can be pivoted with the aid of the hinge
towards the remainder of the circular base. The other three of the four
sides of the rectangle are connected to the remainder of the circular
base area via the predetermined tear line.

[0029] The set of components according to the invention serves for
producing a closure device according to the invention. With the set of
components, the closure device according to the invention is in a
pre-assembled state which enables filling of the chamber with the second
medium, whereupon the last steps of the operation for completion of the
closure device according to the invention are to be performed. The
closure device reproduced with the set of components according to the
invention serves to close a container storing a first medium. The set of
components comprises in the first instance a closure for closing a
through-opening and a lid insert. A filler tube is fastened to the
closure cap on a side of the closure cap turnable to face the
through-opening, in which the lid insert is fastenable via a sealed
connection. The interior of the filler tube closed by the lid insert
forms a chamber for storing a second medium. The formable chamber is
guidable into the through-opening and closed by a lid formed integrally
with the lid insert. The lid closes the formable chamber via a
predetermined tear line, and has an actuating member, with which the lid
is opened by tearing of the predetermined tear line, while the
later-formed chamber is guided out of the through-opening.

[0030] In the set of components according to the invention, the filler
tube is still open, with the result that the second medium can be
decanted into the second filler tube. The filler tube is then to be
closed with the lid insert via the sealed connection, whereupon the
second medium is located in the formed chamber. With this step, a closure
device according to the invention is already completely formed.

[0031] A further set of components serves to produce a closure device in
an embodiment in which the chamber has a sealed opening on a side
turnable to face the closure cap. With the components set, the closure
cap is in a pre-assembled state which makes it possible to fill the
chamber with the second medium, whereupon the last operating steps are to
be carried out to complete the closure cap. The closure device to be
produced serves to close a container storing the first medium. The set of
components comprises, in the first instance, a closure cap for closing a
through-opening and a chamber to be sealed, for storing a second medium.
The chamber is guidable into the through-opening, and is fastenable to
the closure cap on a side of the closure cap turnable to face the
through-opening. The chamber is furthermore closed by lid on a side
turnable to face the interior of the container, and on its side turnable
to face the closure cap it has an opening that is to be sealed. The lid
closes the chamber via a predetermined tear line, and has an actuating
member with which the lid is opened by guiding the chamber attached to
the closure cap out of through-opening, via tearing of the predetermined
tear line.

[0032] In order to produce a closure device with the set of components,
the chamber to be sealed is filled with the second medium via the opening
to be sealed. The opening is then to be sealed, whereupon the chamber is
completely sealed off. In a further step, the sealed chamber is
fastenable to the closure cap, for example, by means of a snap connector.
During filling of the chamber to be sealed and during sealing of the
opening, the chamber may already be within the through-opening.

[0033] The components of the described sets of components preferably also
have those features that are stated as being preferable features for the
components of the closure device according to the invention.

BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Other advantages, details and further developments of the invention
may be found in the description below of preferred embodiments, with
reference to the drawings, which are as follows:

[0035] FIG. 1: A first preferred embodiment of a closure device according
to the invention, after it has been opened;

[0036]FIG. 2: The closure device shown in FIG. 1, before being opened;

[0053] FIG. 1 shows a first preferred embodiment of a closure device
according to the invention, after it has been opened, for which a closure
cap on 01 was removed from a flange 02. The closure device is shown in a
partially cutaway perspective view. The closure device is made of a
plastics material and has been manufactured in an injection moulding
process.

[0054] The closure cap 01 comprises an apron 03 shaped like a cylindrical
casing, which is closed on one side by a closure cap made 04. An inner
thread 06 is formed on the inside of the apron 03. On the inside of the
closure 04, the chamber 07 shaped like a hollow cylinder is arranged
coaxially to the closure cap 01. The lid insert 08 is pressed into the
hollow cylindrical chamber 07 and solidly connected thereto, so that a
sealed connection arises between the lid insert 08 and the chamber 07. A
lid 09, which in the state shown is open, is formed in the lid insert 08.
The lid 09 can be pivoted via a hinge 11 towards the lid insert 08. The
lid insert 08, the lead 09 and the hinge 11 are integrally formed.

[0055] The flange 02 comprises a closure cap connector 12 and a container
connector 13. A through-opening 14 is formed in the flange 2. The closure
cap connector 12 has an outer thread 16 onto which the closure cap 01 can
be screwed with its inner thread 06 and from which it can be unscrewed.
The container connector 13 has a thread 17 with which the flange may be
screwed on to a container to be closed (not shown).

[0056] On the side of the through-opening 14 turnable to face the
container, an upwardly sloping guide edge 18 is formed, which corresponds
with the projection 19 formed on the lid 09, as is shown in detail in
FIGS. 2 and 3.

[0057] The container stores a first medium, whereas the chamber 07 is
provided for storing a second medium (not shown). In the opened state
shown in FIG. 1, the second medium has already dropped down out of the
chamber 07 into the first medium in the container. Consequently, the
chamber 07 is already empty in the status shown.

[0058]FIG. 2 shows, in a closed condition, the closure device shown in
FIG. 1. In this condition, the closure cap 01 is screwed onto the closure
cap connector 12 of the flange 02. The chamber 07 is closed by the lid
09. A predetermined tear line 21 (shown in detail in at the FIG. 8) is
formed circumferentially between the lid 09 and the lid insert in the
form of a weakness in the material.

[0059] The closed chamber 07 stores the second medium (not shown). A
security ring 22, which functions as a guarantee of intactness, is
arranged on the apron 03 of the closure cap 01. The security ring 22 is
connected to the apron 03 via tearable teeth 23.

[0060] The projection 19 of the lid 09 projects beyond the through-opening
14 in cross-section. The lid 09 with the projection 19 is arranged
perpendicularly to the axis of the through-opening 14 in the shown closed
state. In the shown closed state, the projection 19 is arranged at the
start of the upwardly sloping guide edge 18.

[0061]FIG. 3 shows, in a state during opening, the closure device of
FIGS. 1 and 2. During opening, the closure 01 is rotated relative to the
flange 02, in order to unscrew the closure cap 01 from the flange 02.
Consequently, the distance of the closure cap 01 relative to the flange
02 is already increased by comparison with the state shown in FIG. 2. The
security ring 22 is retained on the flange 02, so that the security ring
22 has only limited ability to follow the movement of a closure cap 01,
as a result of which the teeth 23 are torn during further opening of the
closure cap 01, whereupon the security ring 22 is separated from the
closure cap 01.

[0062] In the state shown, rotation of the closure cap 01 has already led
to the projection 19 being guided over the upwardly sloping guide edge
18, as a result of which the distance between the projection 19 and the
chamber 07 has increased, simultaneously effecting opening of the lid 01.
At the same time, the predetermined tear line 21 (shown in FIG. 2) has
torn, and the lid 09 has pivoted via the hinge 11. As a result, the lid
09 is arranged obliquely relative to the axis of the through-opening 14,
so that the lid 09 with the projection 19 can be guided through the
through-opening 14. Even unscrewing of the closure cap 01 from the flange
02 leads to the chamber 07 being drawn out of the through-opening 14.
Consequently, even if the upwardly sloping guide edge 18 is absent, the
projection 19 is, by striking against the inner surface of the
through-opening 14, forced to leave the chamber 07, as a result of which
the lid 09 is flipped open. Due to opening of the lid 09, the second
medium is able to drop out of the chamber 07.

[0063]FIG. 4 shows, in isolation, the closure cap shown in FIG. 3,
wherein in the state of readiness of the closure cap 01 shown, the lid
insert 08 (shown in FIG. 1) is not yet inserted into the chamber 07, with
the result that the latter is not yet in the form of a closed chamber. In
the state shown, in the first instance a filler tube 26 is present which
together with the lid insert 08 to be inserted, will form the chamber 07.

[0064] A circumferentially sealing lip 27 is furthermore arranged on the
inner surface of the sealing cap lid 04.

[0065] In a terminal region, the filler tube 26 has a taper 28 which
simplifies insertion of the formable chamber 7 into the through-opening
14 (shown in FIG. 1), and forms a sealed termination.

[0069]FIG. 8 shows, in isolation in a perspective view, the lid insert 08
shown in FIG. 2. The lid 09 is represented in a closed position, in which
the predetermined tear line 21 is fully formed between the lid 09 and the
lid insert 08. The predetermined tear line 21 is in the form of an arc,
and is formed by a weakness in the material. The projection 19 is formed
integrally with the lid 09 and has the shape of a tongue. A bevel 31 is
formed in the lid insert 08, facilitating outflow of the second medium.

[0070] FIG. 9 shows a sectional view of the lid insert 08 shown in FIG. 8.
The hinge 11, which is formed by a weakness in the material, is also
shown in this view. A tongue 32 is furthermore formed on the lid 09,
which tongue in the closed state of the lid 09 faces a peg uptake 33 on
the lid insert 08.

[0071]FIG. 10 shows the lid insert 08 shown in FIG. 9, after the lid 09
has been opened. On opening of the lid 09, the predetermined tear line 21
(shown in FIG. 8) is torn open. The lid 09 is now connected to the lid
insert 09 merely via the hinge 11. By opening of the lid 09, the peg 32
has been swivelled into the peg uptake 33 by which the peg 32 is
retained. Uptake of the peg 32 in the peg uptake 33 leads to the lid 09
sticking in the opened position.

[0072] In the opened position, the lid 09 is arranged obliquely relative
to the axis of the lid insert 08 and forms with the bevel 31 an oblique
plane on which the second medium can reliably flow down. The oblique
arrangement of the lid 09 in the opened position also leads to the lid 09
with the projection 19 no longer projecting over the cross-section of the
lid insert 08 and thus the cross-section of the through-opening 14 (shown
in FIG. 1), as a result of which the chamber 07 (shown in FIG. 1) may be
guided through the through-opening 14 together with the lid insert 08 and
the lid 09.

[0073]FIG. 11 shows a second preferred embodiment of the closure device
in a perspective sectional view. This embodiment of the closure device,
like the embodiment shown in FIGS. 1 to 3, shows the closure cap 01 and
the chamber 07. The closure cap 01 similarly encompasses the apron 03, on
which the inner thread 06 is formed. The apron 03 is closed on one side
by the closure cap lid 04. Similarly, the closure cap 01 exhibits the
security ring 22 and the sealing lip 27. In contrast to the embodiment
shown in FIGS. 1 to 3, in the embodiment shown in Fig. lithe lid 09 is
formed integrally with the chamber 07. In this embodiment, there is no
lid insert. Another difference is that the chamber 07 is not formed
integrally with the closure cap lid, but is fastened to the closure cap
lid 04 via a snap ring 36. On its side facing the closure cap lid 04, the
chamber 07 is closed by seal 37.

[0074] FIG. 12 shows a further perspective view of the closure cap 01
shown in FIG. 11, wherein the chamber 07 is not yet fastened to the
closure lid 01. As a result of this, in particular the snap ring 36 is
visible.

[0075] FIG. 13 shows, in isolation in a perspective view, the chamber 07,
shown in FIG. 11, wherein the chamber 07 is not yet been sealed and so
does not yet show the seal 37 (shown in FIG. 11). Consequently, there is
an opening 41 still to be sealed on the side of the chamber 07 turnable
to face the closure cap lid 04. Apart from the lack of aid lid insert 08,
the lid 09 with the projection 19 and the hinge 11 is formed in the same
way as in the embodiment shown in FIG. 8. Consequently, the lid 09 is
directly connected to the chamber 07 via the predetermined tear line 21.

[0076]FIG. 14 shows the chamber 07 shown in FIG. 13, after the lid 09 has
been opened.

[0077]FIG. 15 shows a variant embodiment of the lid insert 08 shown in
FIG. 8, with the lid 09 closed. In contrast to the embodiment shown in
FIG. 8, the lid 09 is formed as a rectangular cutout of the circular base
area of the lid insert 08. The projection 19 adjoins the rectangular form
of the lid 09 in the form of a semicircle. The predetermined tear line 21
is formed along three of the four sides of the rectangular form of the
lid 09, wherein one of the two sides is curved correspondingly to the
curvature of the lid insert 08. The hinge 11 is formed on the fourth side
of the rectangular lid 09. Like the embodiment shown in FIGS. 9 and 10,
the embodiment shown in FIG. 15 also shows the peg 32 and the peg uptake
32. The peg 32 is formed as an extension of a reinforcing rib 43.

[0078]FIG. 16 shows the lid insert 08 shown in FIG. 15, after the lid 09
has been opened. The predetermined tear line 21 (shown in FIG. 15) is now
torn. The peg 32 has been accommodated by the peg take-up, 33, with the
result that the lid 09 sticks in the opened position.

[0079] FIG. 17 shows, in cross-section, a variant embodiment of the flange
02 shown in FIG. 6. In this embodiment, no upwardly sloping guide edge 18
(shown in FIG. 6) is present, with the result that the projection 19
(shown in FIG. 1) is removed from the chamber 07 solely in that the
closure cap 01 (shown in FIG. 1) is unscrewed from the outer thread 16 of
the closure cap connected 12. In this arrangement, the projection 19
strikes against the side of the through-opening 14 turnable to face the
inside of the container, wherein, in contrast to the embodiments with the
upwardly sloping guide edge 18, it is unimportant in which direction the
projection 19 is oriented. In the embodiment shown, a plurality of
recesses 44 are arranged along the circumference of the through-opening
14, on a side of the through-opening 14 turnable to face the interior of
the container, which recesses 44 facilitate the flow of the second medium
out of the chamber 07 (shown in FIG. 1).
